JOEL FRANKLIN WOODFORD, OF BROWN S VALLEY, CALIFORNIA.

WRENCH.

SPECIFICATION forming part of Letters Patent No. 614,156, dated November15, 1898. Application led July 11, 1898. Serial No. 685,633. (No model.)

To @ZZ whom t may concern:

Be it known that I, JOEL FRANKLIN WOOD- FORD, a citizen of the UnitedStates, residing at Browns Valley, in the county of Yuba and State ofCalifornia, have invented a new and useful Wrench, of which thefollowing is a specification.

The invention relates to improvements in wrenches.

The object of the present invention is to improve the construction ofsliding -jaw wrenches and to provide one having a reversible stationaryjaw adapted to be arranged to form either a nut or pipe wrench.

A further object of the invention is to enable such stationary jaw to bereadily reversed without disconnecting or moving any of the parts,thereby providing a wrench adapted to be used over Water or undergroundwithout liability of losing any of the parts.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claim hereto appended.

In the drawings, Figure 1 is a perspective view of a wrench constructedin accordance with this invention, the parts being arranged to form anut-Wrench. Fig. 2 is a longitudinal sectional view, the stationary jawbeing reversed to provide a pipe-wrench. Fig. 3 is a detail perspectiveView of the reversible stationary jaw. Fig. 4 is a detail perspectiveView of the outer end of the shank.

Like numerals of reference designate corresponding parts in all thefigures of the drawings.

l designates a lshank provided at its outer end 2, which is slightlyenlarged, with an eye and having at the front side thereof inner andouter parallel shoulders 3, which are beveled, as shown, to form atapering recess. The eye 2 ofthe shank receives a stem 4 of a reversiblestationary jaw 5, which cooperates with a slidin g jaw 6, of theordinary construction.

The reversible stationary jaw, which is substantially triangular in sideelevation, is provided with a smooth flat face 7 and has an inclinedface 8, which is provided with teeth adapted to engage a pipe or rodwhen the parts are arranged as illustrated in Fig. 2 of the accompanyingdrawings. The inner vera tical edge of the reversible jaw is recessed toprovide beveled shoulders 9, and the tapered portion between the beveledshoulders 9 is adapted to iit into the recess or space between theshoulders of the shank, whereby the jaw is held stationary in either ofits positions.

The stem of the reversible jaw, which is arranged horizontally, extendstransversely through the eye of the shank and projects bea yond thesame, the extended portion being threaded and engaged by a nut 10,whereby the reversible jaw is retained firmly in engagement with theshank. The threaded portion of the stem extends sufficiently beyond theshank to permit the nut to be loosened enough to disengage the shouldersof the shank and the reversible jaw, so that the latter may be changedfrom one position to the other without removing the nut from thethreaded stem. By this construction the adj nstment of the reversiblejaw is effected without taking the wrench apart or separating one partfrom another, and the wrench is espe'- cially adapted by suchconstruction for work over water and underground,`as there is noliability of any of the parts being lost.

The sliding jaw 6, which is mounted on the shank, may be operated by ascrew, as illustrated in the accompanying drawings, or any othersuitable means may be provided for effecting such adjustment, and the'shank is provided at its inner end with a suitable handle.

The invention has the following advantages: The 'stationary jaw isadapted to be readily arranged with its smooth flat face, as shown inFig. 1, to enable the wrench to operate on nuts and similar objects, andit can be reversed to bring its toothed pipe-engaging face opposite thesliding jaw without sepa rating any of the parts. The construction forsecuring the reversible jaw to the shank is simple and possesses greatstrength. The nut draws the body portion of the reversible jaw into therecess of the shank, where it is firmly wedged and held against rotarymovement'. l

What I claim isv y In a wrench, the combination of a shank provided withan eye and having parallel shoulders arranged at one side of it adjacentto the eye, a reversible stationary jaw having a nut-engaging face atone side and a pipeengaging face at the opposite side, and provided witha stem extending through the eye and threaded, said stationary jaw beingprovided at its inner end With shoulders interlooking with those of theshank, a nut engaging the threaded stem of the reversible jaw andadapted to be loosened without removing 1o it from the stem to permitthe stationary jaw to be reversed, and a movable jaw mounted on theshank, substantially as described.

In testimony that I claim the foregoing as my own I have hereto alixedmy signature in the presence of two witnesses.

JOEL FRANKLIN WOODFORD.
